Yes — but whether you can unblock it depends on which Outlook you’re using and where the block is happening. Outlook blocks .py files because they’re considered executable and potentially…
Yes — the speed of light is a real, physically measurable speed. The quantity usually denoted c is the speed at which electromagnetic waves propagate through a vacuum. Its defined…
Compared to the GPIO filters discussed in another article in this issue, Mini-Circuits’ 1415-1425 MHz cavity filters are at a significantly higher price point (around $700 at the time of…
Dr Andrew ThornettLichfield Radio Observatory – www.astronomy.me.uk GPIO Labs produces a selection of filters and low-noise amplifiers designed specifically for observations of the neutral hydrogen spectral line at 1420 MHz.…

I am grateful to the help of John Berman on this project – I based the arrangement at LRO on his design. It uses Spectrum Lab Spectrum Analyser software, and…
For a VLF receiving loop, the exact wire length is usually far less critical than people expect. At VLF (about 3–30 kHz): So you are not building a resonant half-wave…
